Update: I did some playing around with the renderer settings and other settings in the options in regards to the filters. I found the problem. It was FFDshow raw video filter the entire time... I didn't even think about it until I saw that it was enabled but Avisynth was disabled. I put everything back to the way it used to be before this post today, and the problem came back. I took off EVR and used VMR9 renderless instead, and the problem went away. But that made me curious, so I checked further into the tweaks like I just mentioned and saw the stuff with FFDshow and Avisynth. So I put everything back the way it was (again) and disabled FFDshow. No artifacting, but now SVP4 wasn't working. Okay, I thought to myself, let's see what happens with Avisynth. So I put Avisynth back on, and voila. SVP4 works, and no artifacting. So, FFDshow is FFDshit I guess. At least as far as EVR is concerned, especially with using bicubic resizing. Using bilinear fixes it for VMR9 renderless though, so if anyone has this same issue I have had to deal with; there you go. That's the fix. Either use bilinear resizing if you really must use FFDshow raw video filter, or just AviSynth filter with whatever you please, cause it actually works by comparison. Perhaps there is more behind the scenes that I don't know about that could make FFDshow work with bicubic without issue, but quite frankly, this basically just gave me every reason I need to never use it again except maybe in certain edge use-case scenarios.
